About authority certificates
To use some WAP services, such as banking services, you need an authority
certificate. Using the certificate can help you to improve the security of
connections between your phone and a WAP server.
You can download the certificate from a WAP page if the WAP service
supports the use of authority certificates. After the download, you can
view the certificate, then save or delete it. If you save the certificate, it is
added to the list of certificates in the phone.
Your phone alerts you if the identity of the WAP server or WAP gateway
cannot be verified or is not authentic.
